You are correct that it is not a normal ROS setup. I am a developer, and it was a client I've been developing.

It turned out to be an XMLRPC problem. The requestTopic method had a variable that always made the address localhost, and therefore the publisher worked on localhost, and subscribers, and services always seemed to work.

This forum says my content is forbidden. If I try to paste data here from XMLRPC calls.

I configured turtlesim on single machine using IP Address instead of localhost, or machine name and it works fine. Problem exists on multiple machines regardless of configuration, and I've gone to the extent of implementing multiple XMLRPC calls to troubleshoot, all seem good: getURI(/controlnode):

No firewall, and I believe I am going to need to look at the xmlrpc method that creates a publishing connection. I am baffled why ros would be connected to client, but think the connection should be the node name instead of hostname or ip....

IP Address 10.42.0.2

WARNING The following nodes are unexpectedly connected: * unknown ( http://10.42.0.2:41859/)->/turtlesim (/turtle1/cmd_vel)

Any other suggestions?

I tried both IP, on main machine, and setting it to localhost in the ROS_MASTER_URI. Neither solved the issue. The following is using IP on computer2, and setting ROS_MASTER_URI of http://localhost:11311 on computer1. (using IP instead of localhost yielded the same result). The /controlnode is

Are you saying the master URL on the destination rosnode should be ip arp, instead of dns name?

I'm unable to publish on /turtle1/cmd_vel with second controller computer, but it works fine on 1 computer. It works fine to send /clear service commands on 1 and 2 computer configurations.

Controller computer name computer2, node name is /rmdmia Running Turtlesim on computer name computer1.

The following is output from roswtf: WARNING The following nodes are unexpectedly connected: * unknown ( http://computer2:51117/)->/turtlesim (/turtle1/cmd_vel)

Found 1 error(s).

ERROR The following nodes should be connected but aren't: * /controlnode->/turtlesim (/turtle1/cmd_vel)

It appears to be a DNS issue, but I've set up the hosts file in both systems with each computer's ethernet ip address, set the ros_ip, and ros_hostname on computer1, and set the ros_master_uri on both systems to the hostname, instead of localhost. Any idea where the configuration is wrong?

Would a custom message definition with a child Object of the message definition type define an infinite loop?

Example Message Definition for CogFoo: Fim x Fim y

Example Message Definition for Fim: float32 a float32 b Fim z
